PROCESS OF MANUFACTURING CIGARETTES WITH TOBACCO WRAPPERS.

SPECIFICATIONforming part of Letters Patent No. 389,975, dated September 25, 1888.

Application filed October 28, 1887. Serial No. 253.647. (No model.)

To all whom, it may concern.-

Be it known that I, IIErNnrorr FRANZ RIE- DEL, a subject of the Emperor of Germany, residingin the city of Dresden, in the Kingdom of Saxony, German Empire, have invented a new and useful Improvement in the Process of Mann fact u rin g Cigarettes with Tobacco Wrap pers, of which the following is a specification, reference being had to the accompanying drawings.

It is understood that for manufacturing cigarette-wrappers of tobacco only those parts of the tobacco-leaf are to be used which are free from coarse ribs. These parts,cut-out to proper size and shape and spread out and flattened, have applied to one edge go in or cement and are rolled up to form cylinders or tubes for The formation or manufacture ofsnchwrappers or cylinders from tobaceo'leaf must, howcver,be accomplished very carefully,in'view ofthe fineness of the material, especially as the outer appearance should be smooth and even. I therefore use for the manufacture ofsuch wrappers a contractible core-body or mandrel which may be easily removed out of the wrapper after it has been formed into a tube thereon, such core having a soft elastic surface, into which the veins and uneven parts of the surface of the leaf may indent themselves if external pressure is applied to the wrapper, thereby allowing the veins and unevenness of thcleafto protrude toward the inside of the wrapper and leave the exterior smooth. The piece of tobacco-leaf to form the wrapper having been moistened and having had cement or gum applied to one of its edges, I roll or lap it around this soft-surfaced core-body to form a tube, and around the so-formed tube, while it is on said core-body, [roll up tightly a temporary wrapper of strong and smooth, but not very thick, paper, which, being harder than the surface of the core-body, presses the veins or uneven part of the tobacco wrapper into the said surface. I then dry the-tobacco wrapper while in the temporary wrapper, and after the drying I produce the contraction of the core-body and withdraw it, leaving the tobacco wrapper within the temporary paper wrapper. I then fill the tobacco wrapper with tobacco by inserting the latter through the end or ends, and after the filling-I unroll and remove the temporary paper wrapper,leavi ng the cigar or cigarette complete.

In the accompanying drawings, which illustrate the apparatus for performing my invcntion, Figure 1 is a longitudinal view illustrate ing the construction of the contractible core body which Iprefer to use in carrying out my invention. Fig. 2 represents a transverse section of the same. Fig. 3 is a transverse sectional view,representing the contractible corebody having a tobacco wrapper rolled around it and showing the temporary paper wrapper asjnst commencing to be rolled around the tobacco for the purpose of enveloping it.

Similarletters of reference designate corresponding parts in all the figures.

The core-body represented has its external portion composed of a piece of soft vulcanized india-rubber tubing, a, of an external diameter nearly equal to the diameter of the cigarette to be produced. Into this tubeis inserted atube of metal, I), split lengthwise. Into this split tube a smooth metal spindle or rod, 0, is inserted, which rod must be of such diameter as to slightly expand the split-metal tube and the india-rubbertube. The core-body having been thus expanded the piece of leaf-tobacco to form the wrapper, having had gum or cement applied to one edge, is rolled or lapped around it and thus formed into a tube. The soft surface of the india-rubber tube presents a soft elastic bed for the tobacco-leaf, the veins and uneven parts of which are pressed into the said surface, leaving its exterior smooth. In Fig. 3 the wrapper (Z is shown thus lapped around the core-body and formed into a tube. The tube having been thus formed, the core body, with the tube upon it, is rolled up within the paper wrapper e. The tobacco wrapper thus enveloped in the temporary paper wrapper is left upon the corebody long enough for the tobacco wrapper and the gum or cement employed for securing its edges to be come dry. The contraction of the core-body is then produced or allowed to take place by withdrawing the central spindle or rod,c, thus leaving the external soft india-rubber tube,a, free to cont-ract,so thatitwill beloose within the wrapper. The latter tube is then withdrawn, and the tobacco wrapper (I, still enveloped within the temporary wrapper c, is filled with tobacco,after which the temporary wrapper or envelope 0 is nnrolled or removed, leaving the cigarette complete.

What I claim as my invention, and desire to secure by Letters Patent, is-

The improvement herein described in the manufacture of cigarettes with tobacco Wrappers, consisting in first wrapping the tobaeeoleaf, of which the wrapper is to be formed, around a contractile body having a soft surface, and cementing its lapping edges to form it into atube, next enveloping the said tube and said body in a temporary wrapper of harder material than the surface of said coritractile body to press the inequalities of the tube into the soft face of the said body, next drying the tube while so enveloped, next pr0- dueing the contraction of the body and withdrawing the same from the tube, next filling the tube with tobacco, and finally removing the temporary wrapper, substantially as here in set forth.

In testimony thatI claim the foregoing as my invention I have signed my name in presence of two subscribing witnesses.
